Application filed October. 9, 1923, Serial No.

This invention relates to machines for making ring mesh fabrics. The object of the invention is to provide asimpler and more ellicient pattern mechanism for selecting one a of two orof a plurality of wires at every formation of a ring of such selected wire.

For this purpose I use a flat or cylindrical pattern plate. of electricity conductive mate rial on the surface of which the pattern is applied ly coating it with non-conductive material. A contact pin is pressed against the pattern plate surface and a relative motion between said pin and said plate is caused coresponding to the motion of the ring mesh in the machine, when the indi vidual rings are formed and when the ring mesh is shifted after formation of one complete row of rings. 7

The annexed drawings show the said pattern mechanism which may be applied to any ring mesh machine or more particularly to the device for feeding a wire to the ring forming tools especially to the knives cutting of? therequired length of wire.

Fig. 1 is a front view and Fig. 2 "a side view of the new mechanism indicating parts of the machine in immediate connection with it.

a is the table of the machine, 6 is a guide block on which the slide 1) is moving lengthwise. The roller with pins to hold and shift the mesh fabric is mounted in a frame 7) resting on the slide Z) and which may be swung backward around the shaft n which is rotatably mounted on the slide 6. 'y and 2 indicate the blocks carrying the tools for forming the rings and for inserting every ring into the neighbouring rings previously formed. Suitable means is provided for inw termittently operating the roller 6 in predetel-mined steps after the completion of each series of rings to vertically shiftthe ring mesh. Provision is similarly made to shift the slide 2') in a stepwise manner to adjust the roller 6 in the direction of its length as the formation of the ring mesh proceeds.

at is an arm mounted on the pivot m which by the action of an electricanagnet 71: and a spring may take two positions bearing respectively against the stop screws 75 76 in the upper part of the arm m two holes or channels m m are provided serving as guideways for two wires of dilferent colours. By swinging the arm m to the right or left hand, one of the said holes m 667,505, and in Germany October 21, 1922.

m is brought into registry with the mecha nism (not shown) to feed a predetermined length of the wire to the cutting-oif knive and the ring forming tools. The mechanism so far described forms no part of the invention and has accordingly been illustrated in diagrammatic form only. vention relates entirely to the means for controlling the operation of the arm m. 7 is the pattern plate'of conductive metal having the pattern applied to its upper surface by'covering the area of the pattern or design with a noncond-uctivelacquer. This plate is placed in a carriage 7 provided with rollers 7" running in guide ways 7' of a supporting plate 7, which is attached'by rods to the table a.

dis a slide guided on a rod (Z fixed to the rods in a direction rectangular to the guideways f (Z is a contact pin pressed by spring (Z against the surface of the pattern plate f. (Z is an electric conduit leading to the electromagnet 7;, which itself is connected by the wire (Z to the machine frame, the latter being in conductive connection with the lower side of the pattern plate f.

Motion is imparted to carriage f from the shaft n. This shaft is connected with the shaft of roller 72 by a link belt n to adopt the same motion as roller 72 viz, a stepwise rotation after the completion of every series of rings, shifting the ring mesh vertically the distance of two consecutive series of rings. The shaft 91 is proviced with a key a and a roller h is mounted on it, free to slide in axial direction but rotating together with it. A tori; a mounted on the table a prevents roller h from participatingin the axial motion of shaft a, when the slide?) is fed stepwise at the formation of a ring. The roll it has the same diameter is roller 6 and has wound on its circumference a string ]L1. This string runs over guides 72 If h to the carriage f is fixed thereto and goes on over guide 7L and carries the weight 7L. Thereby the Carriage f is moved at every movement of the roller 6 the same length in its guideways f as the ring mesh is moved vertically.

The motion of the slide cl is caused by a string 0. This string is attached to the end of shaft 91 or may be attached to any point of the slide 6 and runs over guides c 0 to slide at, is attached thereto and runs on over guide 0 to carry the weight 0*.

The present ini Thereby the shifting stepwise motion of slide 6 is transmitted to pin 6Z The pin (Z travels in consequence of the two-described motions over the whole stir ductive coating the arm at returns to its prior posit-ion by the action of spring k Now what I claim is:

1. In a ring-mesh machine including ringtorming tools and means for feedingv the ring-mesh horizontallyv and vertically in predeterminedsteps as the formation of the ring-mesh proceeds, the combination of a pattern plate of conductive material, a pattern applied to its surface making itnonconductive for the areaofthe pattern, a contact pin'pressed against the surface of the pattern, means to cause a relative motion between said" pin and said pattern plate to correspond with the vertical motion of the ring-mesh after completion of a row of rings and with the horizontal motion at the formation of every ring a movable'guide for a plurality of wires whereby the latterv are guided to the ring forming tools and an electric circuit comprising the said contact pin, the said pattern plate and means to actuate the said movable wire guide by closing and breaking the current in the said circuit. A

2 In a ring-mesh machine including ringforming tools and means for feeding the ring-mesh horizontally and vertically in predetermined steps as the formation of the ring-mesh proceeds, the combination of a pattern plate of conductive material, a pattern applied to its surface making it nonconductive for the area of the pattern, a contact pin pressed against the surface of the pattern, means to cause a relative motion between said pin and said pattern plate corresponding to the motion of the ring mesh with relati'on'to ring forming tools an electric circuit traversing the said pattern plate, a movable wire guide for a plurality oi wires and means to actuate. the said movable wire guide by closing and breaking the circuit by the pattern on the patern plate.

In a ring-mesh machine as specified in claim two a pattern plate located below the 7 machine table, a contact pin pressed against the surface of the pattern plate, and means transmittingthe lengthwise motion and the vertical motion of the ring mesh to the pat tern plate and contact pin.

4:. In a ring, mesh machine including ring forming tools; means for feeding the ring mesh horizontall and vertically in predetermined steps as the formation of the ring mesh proceeds in combination, and means to feed a plurality of wires to said ring for ingtools, the combination ofa pattern plate of conductive. material having a pattern applied to its surface making the same nonconductive for the area of thepattern, an electric contact member adapted to contact with said pattern, said pattern and said contact member being relatively movable, a corn nection between the means for moving the ring mesh in the horizontal direction and the said movable member to move said movable member in accordance with the horizontal feed of the-ring mesh and a second connection with the vertical. feeding means and said movable member to move the movable member in accordance with the vertical feed of. the ring mesh.
